We know Amazon's proprietary app store is (intentionally) limited—but according to Mashable, nowhere near as limited as we thought. Unofficially, you can bend the app rules and load up Nook on your Kindle. Kinky!

Mashable's Christina Warren was able to get unapproved apps onto her Kindle Fire by downloading generic Android app store GetJar—all she had to do was lie about the device she was using. Once that's in place, a range of apps Amazon hasn't sanctioned are available, including, of course, the highly ironic (and functional, I guess!) Nook software, giving you access to both Amazon and Barnes & Noble's libraries. There—now you've saved yourself another $250. [Mashable]
